Fine particles (PM2.5) are the main cause of reduced visibility (haze) in many parts of the world. They can also cause acidification of lakes, depleting nutrients in soil, damaging sensitive forests and farm crops, affecting the diversity of ecosystems and contributing to acid rain effects.

Numerous scientific studies have linked particle pollution exposure to a variety of problems, including premature death in people with heart or lung disease, nonfatal heart attacks, irregular heartbeat, aggravated asthma, decreased lung function, increased respiratory symptoms, such as irritation of the airways, coughing or difficulty breathing.
